The OVP can be installed directly on the flange using existing flange bolts with the FMFB Mounting Bracket. This kit is furnished with two nickel-plated copper adapter plates which are attached to the OVP and secured to the face of the flange using the existing flange bolts. To install these devices using existing flange bolts, the flange must have a machined, unpainted outer face to mate to the bus bars. An appropriate anti-corrosion compound is included for the bracket to flange interface.
